BACKGROUND: The aim of this study was to compare the cardiovascular changes followed by laryngoscopy with the McCoy laryngoscope blade with those followed by laryngoscopy with the Macintosh laryngoscope blade. METHODS: Forty eight patients were randomly divided into two groups. Following induction with fentanyl 2 mcg/kg and thiopental 5 mg/kg, and muscle relaxation with vecuronium 0.1 mg/kg, the vocal cords were visualized with either the McCoy or the Macintosh laryngoscope blade, then tracheal intubation was performed. Heart rate and arterial blood pressure were measured just before and after laryngoscopy, and 1, 3 and 5 min later. RESULTS: There was a significant increase in both heart rate and arterial blood pressure after tracheal intubation using the Macintosh laryngoscope. Also, use of the McCoy blade resulted in a significant increase in both heart rate and arterial blood pressure. CONCLUSIONS: There was no significant difference on arterial pressure and heart rate to laryngoscopy and tracheal intubation with either the McCoy blade or the Macintosh.

This study is aimed at developing a cardiac rehabilitation program and enlightening the effects of the program on patient's health behavior compliance, cardiovascular functional capacity, and quality of life. Using a quasi-experimental approach the nonequivalent control group pretest - posttest design was accepted for this study. The subjects of this study consisted of 55 patients with ischemic heart disease at the Cardiac Center of 'G' Hospital located in Inchon from May 1, 1998 to April 30, 1999. The patients were divided into two groups: the experimental group, which participated in the cardiac program with 30 patients and 25 patients of a control group were not involved in the program. There were two phases in the cardiac rehabilitation program: the first phase was a team approach education. It focused on reducing the risk of ischemic heart problems. The second phase was individual training by using a home based exercise program, which was comprised of 8 weeks, three sessions per week, 40-60 minutes per session, and followed by consultation. Every session involved 20-40 minutes of aerobic exercise at 40-60% of heart rate reserve, 11~13 RPE and 10 minutes of warm-up and 10 minutes of cool-down exercises. The experimental tools for the study were the health behavior compliance scale developed by Lee, Yoon-hee (1992), and quality of life scale developed by McGirr et al.(1990). RPPsubmax were measured by the treadmill. The collected data was processed by SPSS and analyzed by X2test and t-test. The results of this study were as follows: 1. The health behavior compliance in experimental group was significantly increased (t=5.091, p=.000) when compared to the control group. 2. RPPsubmax also decreased significantly in the experimental group when compared to the control group(t=-2.109, p=.040). 3. The quality of life significantly improved in the experimental group (t=3.853, p=.000) as compared to the control group. As the above results of this study revealed, the effectiveness of the cardiac rehabilitation program of the study was confirmed. It increased the health behavior compliance for reducing the risk of further coronary events, enhanced the cardiovascular functional capacity, and eventually improved the patient's quality of life.

OBJECTIVES: Estimation of the anterior lower uterine segment (LUS) thickness difference who underwent prior cesarean delivery measured with transvaginal sonography at or after 36 gestational weeks (sonographic thickness) and a ruler during elective cesarean section (operation thickness) Methods: One hundred sixty women who underwent prior cesarean delivery had the thickness of their LUS measured with transvaginal sonography at or after 36 gestational weeks. The LUS thickness was measured with a ruler during elective cesarean section. We compared group I whose LUS was fairly well visualized 4 cm or more from the uterine cervix to group II which had less than 4 cm. RESULTS: The mean sonographic thickness of LUS was 1.7 0.8 mm and that of operation thickness was 1.9 0.5 mm. The mean difference of the two (thickness difference) was 0.5 0.5 mm. In 31.3% the sonographic thickness was same as the operation thickness and in 70.7% of the total with 0.5 mm or less difference, the sonographic thickness could be regarded as accurate. The thickness difference with the sonographic thickness with 2 mm or more was smaller than those with 1 mm or less (0.4 0.5; 0.6 0.6) and that of group I was smaller than that of group II (0.4 0.4; 0.9 0.6) (p< .05). CONCLUSION: The thickness difference was 0.5 0.5 mm and it was smaller when the LUS thickness is 2 mm or over, clearly visible 4 cm or over from the cervix.

Brain size is a useful parameter describing ontogenic character and function. Despite its potential contribution to functional study and diagnosis of disease, it has been hampered by poor assessment tools in vivo and postmortem changes. Recent development of medical imaging techniques such as MRI and CT enable us to understand brain structures in vivo. Many morphometirc studies of the brain has given us new insights in the field of functional neuroanatomy and neuropsychiatric diseases. In spite of these advances, volumetric data of normal Korean brain is not available yet. As an initial approach to Korean standard brain size, we measured the cerebellar volume between 20 and 80 years old Koreans. The MRI films free from lesions in brain was analyzed and measured by NIH image program. The Korean cerebellar volume were ranged between 86.2cm(3) and 141.3 cm(3) and average male cerebellum volume was significantly larger than that of female[male : 118.2+/-11.2cm(3)] > female : 108.0+/-9.6cm(3), P=0.1021E-07<0.05]. And we could not find volume change according to aging process. This is the first report on normal Korean cerebellar volume and the presence of gender difference in the Korean cerebellar volume. These data will be used for the standard useful in studying cerebellar function and cerebellum associated disorders in the future.

Forth-nine patients with clinically nonfunctioning pituitary adenomas were evaluated clinically, endocrinologically and morphologically in this study.The results obtained were as follows.1) The mean age was 47.1 years(range 23 to 76 years), and 22 were male(44.9%) and 27(55.1%) female.2) The major clinical manifestations of male patients were visual disturbance(72.7%), headache(54.5%), loss of libido(45.5%), but those of female visual disturbance(59.6%), headache(48.1%), amenorrhea(48.1%), loss of body hair(25.9%), and galactorrhea(22.2%).3) All were macroadenomas evaluated by CT scan, and in the male patients 16(72.7%) were grade III and 6(27.3%) grade IV by Hardy classification, and in the female patients 6(22.2%) were grade II, 12(44.4%) grade III, and 9(33.3%) grade IV.4) The elevation of serum prolactin were observed 7(31.8%) out of male, and 24(88.9%) of female.5) Combined stimulation test revealed that GH insufficiency was 89.6%, ACTH 58.9%, LH 58.7%, FSH 51.1 %, and TSH 50.0% and hormone insufficiency more than 4 pituitary hormone was 54.2%.6) Prolactin response to TRH decreased in 12(70.6%) of 17 patients with normal basal prolactin, and 19(76.0%) of 25 with elevated prolactin.7) Immunohistochemistry revealed that null cell adenoma was 57.1%, gonadotrope adenoma 26.5%, plurihormonal adenoma 8.0%, silent corticotrope adenoma 4.0%, thyrotrope adenoma(2.0%), and lactotrope adenoma(2.0%).8) The ultrastructural characteristics examined by electron-microscopy were similar despite of immunohistochemical differences.In summary, the prevalance of clinically nonfunctioning pituitary adenoma was middle aged men and women, and their main symptoms were visual disturbance and headache. Hyperprolactinemia and pituitary hormone insufficiency more than 4 hormone were observed commonly. Most of them were null cell adenoma and gonadotrope adenoma examined by immunohistochemistry. Further study using modern techniques: cell culture, subunit-immunostaining. And Northern blot analysis of mRNA for pituitary hormone or subunit, will be needed to clarify null cell adenomas.

BACKGROUND: To evaluate the left heart function, left atrial pressure(LAP) has been monitored directly via LA catheter and indirectly via Swan-Ganz catheter. But indirect pressure monitor cannot often reflect the LAP precisely. We compared the LAP via LA catheter with central venous pressure(CVP), diastolic pulmonary artery pressure(DPAP) and pulmonary capillary wedge pressure(PCWP) by Swan-Ganz catheter. METHODS: Eleven cardiac-surgical patients whose LAP measurements were needed for clinical management were the subjects of this study. The CVP, DPAP and PCWP by Swan-Ganz catheter, and LAP were measured just after cardiopulmonary bypass, just after sternal closure, after 6 hours and 18 hours from the end of operation. And we divided them into two groups which consisted below 35 mmHg(group I) and over 35 mmHg(group II) of systolic pulmonary artery pressure(SPAP), and compared two groups. RESULTS: In group I, the LAP, CVP, DPAP and PCWP was 11.7+/-3.9 mmHg, 10.5+/-3.9 mmHg, 12.5+/-5.1 mmHg and 12.5+/-4.4 mmHg respectively, and correlation coefficiency of LAP with CVP, DPAP and PCWP was 0.7478, 0.7128 and 0.9002 respectively(p<0.05). In the group II, the LAP, CVP, DPAP and PCWP was 16.5+/-3.2 mmHg, 12.8+/-2.9 mmHg, 23.4+/-3.8 mmHg and 20.8+/-4.7 mmHg respectively and there was no correlation between LAP, CVP, DPAP and PCWP. CONCLUSIONS: The Swan-Ganz catheterization for the estimation of LAP is useful in the patients without pulmonary hypertension, but in the patient with pulmonary hypertension, CVP, DPAP and PCWP do not reflect the LAP.
